Stars with a city lawyer (9)
I believe the answer is:
andromeda
'stars' is the definition.
(Andromeda is a constellation)
'with a city lawyer' is the wordplay.
'with' becomes 'and'.
'a city' becomes 'rome' (Rome is an example).
'lawyer' becomes 'da' (abbreviation for District Attorney).
'and'+'rome'+'da'='ANDROMEDA'
(Other definitions for andromeda that I've seen before include "Constellation with galaxy" , "group of stars" , "Greek maid seen in Milan" , "princess barely chained to rock" , "Galaxy nearest ours" .)
